One of the problems is that the physical care (whether at home or in a care home) is only part of the problem. For example, you can get someone to make sure you have taken your medication, help to wash and dress you , make sure you have eaten etc. But there has to be more to “living” than that. What about stimulating conversation, a friendly chat, entertainment etc?
My grandma was very lucky as I spent hours with her looking at photos, watching tv, talking about the news, sharing cake and tea. We included her in everything we did as a family (and yes it was very difficult sometimes) .
Old people whether they are in their own homes or a care home, need more than just the basic care package.
